Our R717 (ammonia) & CO₂ cascade refrigeration cold storage is engineered around environmental protection, high efficiency and stability. Equipped with temperature‑matched PU insulation panels, an intelligent monitoring platform and an AI intelligent defrosting system, it provides full‑process customized solutions for full‑temperature cold storage.
The cascade system adopts a CO₂ low‑temperature stage + R717 high‑temperature stage structure, covering a temperature range of −60°C to +15°C with optimal efficiency at −40°C to −18°C. Both are natural refrigerants with ODP = 0, featuring high safety, stable operation, low maintenance and excellent compatibility with green cold chain upgrading. The cold storage provides four customizable temperature zones: standard freezing, low/high‑temperature refrigeration, as well as special zones including controlled atmosphere, constant temperature and humidity, buffer rooms and deep‑low‑temperature storage, suitable for food, pharmaceuticals, biological samples and precision equipment.
The IoT‑based intelligent monitoring system realizes real‑time data collection, three‑level early warning, remote control and energy efficiency optimization. The AI defrosting system enables on‑demand precise defrosting, significantly reducing energy consumption, minimizing temperature fluctuation and extending shelf life.
We provide one‑stop customized services from demand survey, design, construction and commissioning to professional after‑sales support with dedicated safety maintenance for R717 and CO₂ systems. Widely used in food processing, cold chain logistics, pharmaceutical storage and scientific research, it delivers safe, efficient and eco‑friendly full‑temperature storage solutions.
